Black dial, black strap, steel case: the Mido Commander Chronometer M021.431.16.051.00 is the most understated member of its family, and that is exactly why it works. It goes with everything, from a charcoal suit to a leather jacket, and it hides a movement that most watches at this level cannot match.

Inside is the Caliber 80 Si, a COSC-certified chronometer movement with a silicon hairspring. Silicon is light, non-magnetic and stable across temperature changes, which helps the watch hold its rate day after day, and the 80-hour reserve means you can rotate it with other watches without constant resetting. A day-and-date window sits at 3 o'clock.

The design comes from the Commander line, which Mido has produced since 1959 and styled after the arches of the Eiffel Tower. Here the 40mm case is paired with a black leather strap and butterfly clasp for secure, easy wear.
